Different representation of UUID in Java Hibernate and SQL Server

Question

I am trying to map a UUID column in POJO to SQL Server table column using Hibernate.

The annotations are applied as follows:

@Id
@Genera         


        

Answer 1

Microsoft databases use GUIDs. It is Microsoft's implementation of the UUID standard.

This being said, you should use the guid generator.

@Id
@GenericGenerator(name = "generator", strategy = "guid", parameters = {})
@GeneratedValue(generator = "generator")
public String getId() {
    return id;
}

guid uses a database-generated GUID string on MS SQL Server and MySQL.

Also, have you set SQLServer2012Dialect? This also might solve some future issues.
